Danfoss Heating Control

Did anyone ever had a problem with Danfoss heating controllers? I have several in my flat but sometime one do not connect anymore and start blinking. I bought now 2 times a new and after every unboxing i just startet it for testing, but all the thing does is wild blinking in the display and not connection to the wave controller. Very annoying for new device.

I had now 2 times broken devices and now i stoped ordering new devices because all had the same problem. Are there good alternatives for Danfoss climate controller out there available in Europe/Germany?

Are you talking about thermostats like the Danfoss living Connect?

yes thermostats

I use de Devolo Home control thermostat, itis the same device but rebranded with another firmware.
In the year i use this device never had any problems.
